Air is compressed from 140 kPa and 320 K to 1200 kPa in a two stage compressor with intercooling between stages. The intercooler pressure is 320 kPa. The air is cooled back to 320 K in the intercooler before entering the second compressor stage. Each compressor stage is isentropic. Use the PG model.
